Totally agreed. cell-index should -only- be about correlating a given device in an ASIC with some shared register (an example coming to mind is clock control registers with one bit per cell) etc... For the rest, well, use aliases :-) Ben. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
